Read the entire instruction manual before beginning installation. Some stock parts will
be used in reassembly.
This high capacity oil tank installation is specifically designed for the 2006-2008 Z06
Corvette. The 2009-2010 Z06 and ZR1 Corvette are already equipped with a high
capacity tank of similar volume.
Under prolonged high cornering loads such as those found on a banked race track with a
vehicle with racing slicks, some customers have reported low oil pressure on the 20062008 Z06 Corvettes. The Lingenfelter Performance Engineering modified oil tank design
was developed to eliminate this problem. Designed to fit in the stock dry sump oil tank
location with no modifications to the vehicle, the Lingenfelter modified tank increases
system capacity by roughly 3 quarts, taking total capacity from 8 quarts to 11 quarts and
increasing the capacity of the tank alone from 6 quarts to 9 quarts (a 50% increase).
The added oil volume will also help reduce high oil temperature spikes under certain road
racing conditions by increasing the amount of fluid in circulation and the amount of time
it takes to heat up that fluid.
The factory oil dipstick will still function correctly and the same indicator mark is used to
indicate the new “full” oil level.
Included with the modified oil tank are new seals for the oil lines as these should be
replaced every time the lines are disconnected.
When referencing the side of the vehicle, the driver side of the vehicle is considered the
left side and the passenger side of the vehicle is considered the right side of the vehicle.
GM sells the Original Equipment Manufacturer (OEM) lower oil tank as a part of the entire
oil tank assembly. Due to the lack of availability of just the OEM lower oil tanks from
GM, Lingenfelter Perfomance Engineering (LPE) requires the core out of your vehicle
in exchange for the modified lower oil tank. After recieving the LPE modified lower oil
tank, thoroughly clean the stock lower oil tank and send it back to LPE for a core charge
refund.
1. Open the hood of the vehicle. If you have
been driving the vehicle, allow the vehicle to
cool down for a few hours before starting this
installation.
Page 2.
2. Raise the vehicle with a vehicle hoist or a
jack and jackstands. Be careful to follow the
GM lifting procedures on the Z06 Corvette
due to the aerodynamic components being
easily damaged and the low ride height of the
vehicle.
3. Using a 15 mm socket, remove both drain
plugs from the oil pan to drain the oil.
IMPORTANT: Be sure to have an oil drain
pan to catch the oil.
4. Allow all oil to drain out of the oil pan.
Remove the oil filter by turning it counter
clockwise by hand or using an oil filter
wrench.
5. After all of the oil has drained out, replace the
oil filter with filter part number UPF48R (PN
12626224) and torque the filter to 18lb-ft (25
Nm). Replace both drain plugs and torque
both of them to 18lb-ft (25 Nm).
GM has released a filter with a higher
burst strength for use on the 2009 and
new Z06 and ZR1. LPE recommends the
use of this filter in all Z06 applications.

6. Remove the passenger front wheel using a
19mm socket.
NOTE: some aftermarket rims require you to
use a coated socket to avoid scratching your
rims.
7. Using a 7mm socket for the outer bolts and a
10 mm socket for the inner bolts, remove the
passenger front fender liner.
8. Remove the two (2) plastic push pins from
the side of the fender liner by using a fork pry
tool. Pull out on the center (smaller) pin until
it pops out, then remove the whole push pin.
IMPORTANT: Be careful not to damage the
push pins, they will be re-used.
9. The liner is attached to the fender with metal
push-clips. Start with the lower portion of the
liner and pull the liner strait out of the fender.
Page 4.
10.With the liner removed, locate the bolt on the
bottom of the fender directly under the front
of the passenger side door. Remove this bolt
using a 7 mm socket (this is needed to push
the fender out of the way slightly to make
way for the removal and installation of the
tanks).
11.Mark one of the vapor lines as well as its
respective port with a piece of tape (or
equivalent) and remove the vapor lines from
the top of the tank. This is done by pushing
the small tabs on the ends of the lines
clockwise and pulling outward.
12.Using a 10 mm socket and extension, remove
the two bolts from the bracket holding the
middle of the tank. Be careful not to drop the
two bolts once you remove them.
13.Using a 10 mm socket and extension, remove
the bolt on the top of the tank located directly
between the oil cap and the fender.
Page 5.
14.On the bottom of the tank remove the oil
temperature sensor by first disconnecting
the harness and then unscrewing the sensor
using a 19 mm wrench. Inspect the sensor
for damage as you will be using this sensor
again.
NOTE: The sensor may be removed after the
tank is removed from the vehicle instead of
while it is still in the vehicle.
15.Remove the oil lines from the bottom of the
tank by using a 13 mm wrench to remove the
two bolts directly under the oil lines. Be sure
to have an oil pan below to catch any residual
oil that may drain out of the tank.
16.At this point in the installation it is
recommended to have another person to help
remove and place the oil tank. While one
person is holding the top of the tank, remove
the two (2) 15mm bolts on the mounting
bracket on the bottom of the oil tank that
secure the tank and bracket assembly to the
vehicle.
17.Move the bottom of the tank out of the way
and remove the oil lines. Be sure to point the
lines into the oil pan as residual oil will most
likely drain out.
Page 6.
18.Remove the tank from the car by having one
person pull the tank down through the bottom
of the fender while the other person carefully
moves the tank out of the way of the wiring
harness as well as any other obstructions.
19.Mark the top and bottom portion of the tank as
shown. You will use this to reference putting
the assembly back together correctly, notice
the location of the oil line fittings on the stock
lower tank.
20.Using a 13 mm socket and extension, remove
the eight (8) nuts and bolts on the tank to
separate the top and bottom of the tank. You
will need a deep well socket or an open end
wrench to remove the two bolts (in which the
tape is in between) indicated to the left.
21.Inspect the top of the tank for damage or
corrosion. Be sure to wipe the mounting
surface clean before installation on the new
tank.
Page 7.
22.Using a 13 mm socket, remove the two
(2) mounting brackets from the old tank by
removing the four (4) bolts on the brackets.
Install the old brackets to the new tank and
torque to 18 lb-ft (25 Nm).
23.Using a 19 mm socket, replace the oil
temperature sensor and tighten to 15 lb-ft (20
Nm) of torque.
24.Remove the oil screen from the old tank by
gently twisting, wiggling, and pushing the
screen towards the outside. Install the oil
line screen onto the new tank by pushing the
screen into the inlet bore from the outside of
the tank until the locking tabs locate in the
grooves.
IMPORTANT: The oil screen is fragile and
expensive to replace so handle with care.
25.Inspect the O-ring and engine oil tank gasket
from your old tank to your new tank
Page 8.
26.Line up the holes on the top and bottom tank
and also make sure that the bolt holes line
up correctly. Line up the tape on the top tank
with the oil line fittings on the new lower tank.
Remember your marking that you made on
your old lower tank and compare it with the
new tank.
27.After aligning the tanks, using a 13 mm socket
and extension, torque the eight (8) bolts to
18 lb-ft in an 8-bolt star pattern (25 Nm).
Remember that you will need a deep well
socket to torque the longer bolts. The tape
used to mark the tank should be in between
the two (2) longer bolts.
28.Replace the two oil seals on the bottom oil
tank lines with the supplied oil seals (GM part
# 15217990). Make sure that the rubber side
of the seals are facing toward the tank.
29.Place the tank inside of the passenger front
fender with the tank’s expanded oil volume
section pointing towards the rear of the
vehicle.
Page 9.
30.With one person guiding the top of the tank
up, slide the tank in through the bottom and
line up the bolt holes to the brackets on the
bottom.
NOTE: Be careful not to pinch any of the
wiring harnesses in the way.
31.Using a 15 mm socket, bolt the two (2) bottom
brackets of the tank to the frame rail and
torque to 27 lb-ft (36 Nm).
32.Install both oil lines and, using a 13 mm
socket, torque the two (2) bolts to 16 lb-ft (22
Nm).
33.Using a 10 mm socket, install the three (3)
bolts on top and torque each to 89 lb-in (10
Nm).
Page 10.
34.Remove the oil fill cap and fill the tank with 11
quarts of oil and check the dipstick. If the oil
level reads slightly high this is okay.
35.Start your car and check for oil pressure.
Once the pressure rises get out of the car and
visually inspect the oil tank for leaks. Turn off
your car.
36.Check your oil level on the dipstick to ensure
proper oil level has been reached. Please
read the steps on page thirteen (13) on
checking your oil on this dry sump system.
37.Position the fender back into place and, using
a 7 mm socket, install the bolt that was taken
off in step 9.
Page 11.
38.Push the liner back into place and replace
the two (2) push pins that were taken out by
inserting them with the pin in the out position,
and once inserted into the hole push the pin
into the hole and it will lock into place.
39.Using 7 mm and 10 mm sockets, replace the
four (4) bolts that were removed from the
fender liner.
40. Torque the wheel lug nuts to 100 lb-ft
(140 Nm). Be sure to use the proper torque
sequence for a 5 bolt wheel. Remove jack and
jack stands and enjoy your new oil tank.
41. Be sure to tell anyone servicing your
vehicle about the expanded oil capacity.

This is the GM factory Z06 and ZR1 recommended procedure. The LPE oil tank does not
change the proper level marking position.
How to Check Your Oil In This Dry Sump System:
• Start the engine and warm it up to around 175o F (80o C) coolant temperature.
• When the engine reaches the recommended temperature, turn off the engine.
• Wait at least five (5) minutes (but no more than twenty (20) minutes) for the oil to settle back into
the engine.
• Remove the dipstick from the external oil tank and clean off the oil with a lint free rag.
• Re-insert the dipstick and check the oil level on the cross-hatched area on the dipstick. Any level
that is within the cross hatches is considered normal and your oil level is okay.
• Please refer to your owners manual for more information on the dry sump system.
